No one has ever seen the world exactly as it is. Ever.
It is difficult to comprehend, but everything you have ever seen, smelt, heard or felt is merely your brains interpretation of incoming stimuli and as such, is massively open to interpretation.
Add into the mix that everyone's personal experience is heavily tinted by personal prejudice, taste and opinion, it is clear to see that no two people view or experience the world in exactly the same way. And it is easy to become entrenched in the idea that your world view is the correct/only one.
Art (including spoken word tradition) is the only way to truly see the world from another person's viewpoint and, in my opinion, no artform can convey such a wide ranging set of ideas, views and emotions as literature.
We owe it to ourselves to read as wide a variety of ideas as possible so that we can venture out of our limited view of the world and see it as it's meant to be. Open to interpretation.
